I was wondering if there was a way to add descriptions/ comments to files e.g. PDFs. I have a lot of PDFs and often I forget where the file came from, why it's a good reference, what reading list it's from, etc. It's pretty astounding that this has proved so difficult to do! My ridiculous workaround is to add all that sort of information to the title of the file, leading to titles like: "@@PDE and Martingale Methods in Option Pricing -- A. Pascucci (Bocconi & Springer 2011)(11)" (The first @ denotes that this is a good reference, the second @ denotes the fact that I own a copy. Other bits mean other things.).
I've read that comment and descriptions are not supported by PDF files, and nobody seems to be able to figure out how to do this. If you go to file>properties>description, you can add a description, but it does not show up in the description column in Explorer, and it seems the only way to read them is via opening the files individually, and then file>properties>description. I doubt that Windows has access to that information when it does searches.
My guess is that it cannot be done except with some special program, and I have installed many including "PDF shell tools", "Total Commander", and "FileMeta" and none of them have worked.
A solutions would be much appreciated!
